My invention relates to improvements in electric toys, and it consists'm the} combinations, constructions herein described and claimed.

a An object of m an electric toy w 'ch may be of any desired construction or formation, but for the purpose of illustration it is shown' in the form of a trucki which is adapted to be operated electrical y by remote control.

A. further object of my invention is to provide a device of thetype described in which the truck has a novel means for normall holding the front'wheels-in the forwar moving position.

A further object of my invention is to provide a device of the type described which has novel means for steering the truck, to one side or to the other.

A further object of my invention is to provide a device of the type described which as novel means for retaining complete electrical connection with the truck irrespective of its position with the garage.

Other objects and advantages will appear in, the following specification, and the novel features of the invention will be particularly pointed out in the a pended claims.

and arrangementsinvention is to provide.

re 6 a section along the line 6-6 which is disposed an insulating member 5. Conductor rings 6, 7, 8, 9, and 10 are mounted upon the insulating member 5 at spaced apart positions. A plurality of terminal posts v11 are electrically connected to the rings 6 to 10 inclusive. Conductors 12, 13, 14, 15, and 16 are electrically connected to the rings 6 to 10 inclusive through theterminal osts 11. I c

, A pivotal contact, member 17 is provided .00 with a central shaft 18, which. extends through a bearing 19 in the insulating memher 5 and is arranged'to pivot with respect thereto. Resilient contact members 20 are disposed at spaced apart positions upon' the inner surface of the rotating member 17. and in frictional enga ement with the rings 6 to-10 inclusive. ({bnduct'ors 21, 22, 23. 24, and 25 are electrically connected to the rings 6 to 10, inclusive, through the resilient contact member 20. 1

The conductors 21 to 25 inclusive extend through a tubular member 26 and a tubular member 27, the latter being carried by the truck member 1. The truck member 1 is 7: provided with a frame 28 which has a rear axle 29 rotatably carried thereby. Wheels 30 are mounted upon the axle 29 at the outer. ends thereof. A driven ear 31 is rigidly mounted upon the axle s aft 29 and is in mesh with a drive gear 32. The drive gear 32 is ri 'dly mounted .upon a motor shaft 33 whic is carried by a motor 34. Electromagnets35 and 36 are carried by the frame 28 and are disposed in close proximity to so steering levers 37 and 38 respectively. Front wheels 39'are rotatably mounted on axles such as that shown at 39* in Figure 4. Each axle is rigidly secured to a lever such as that shown, at 37. Secured to the o0 lever is an armature 39 adjacent to one end of the electromagnets 35 and 36. The armature in' turn is pivotally mounted at 39 on a cross member. 39" carried by the frame 28. ,As will be seen from Figure -1, there to are two levers 37 and 38, these levers-being on opposite sides of the frame. Each lever ispivotally connected to a bumper or con- J necting member 40, the pivotal connection of'the ever 37 being shown at 37 in Figure [c0 4. The connecting member 40 is provided with an inwardl extending lug or pin 41 which is normally held in alignment with the center line of the frame b means of resilient sprin members 42 and 43 which are carried by the frame 28. When one of the solenoids is actuated, as for instance the solenoid 35, it will swing the armature 3 9 inwardly thus turning the axle 39, and it will also cause a shift n of the member 40 against the action of. tl ie spring 42. The movement of the member 40 will cause a corresponding shifting of the axle of the opposite wheel 39 in the same direction and to the same extent thus turning both wheels simultaneously; The energizing of the oppositesolenoid 36- will cause a correspond- 1n movement in the op osite direction. W en the solenoids are e-energize'd, the wheels are brought to their central position by means of the springs 42 or 43.

From the foregoin descri tion of the various parts of the device, t e operation thereof may be readil understood. It will be noted that the positive conductor 44 extends to a transformer 45. The positive conductor 46 extends from the transformer 45 to a switch 47 which has arced shaped contact plates 48 and 49 thereon. Conductors 12 and 13 are in electrical connection with the plate 49, as shown, and the conductor 14 is in electrical connection with the contact plate 48. The conductor 46, as shown, is in electrical connection with the contact plate 48. A negative conductor50 extends to the transformer 45 and a negative conductor 51 extends from the transformer 45 to the shaft 18 and to a ground 52. The magnetic coils 35 and 36 are connected to the ground 52 through conductors 54 and 55 respectivej ly. A steering switch 56 is arranged to electrically connect either of the conductors 15 or 16 with the positive conductor 46 through a conductor 57.

With the switch 47 in the position shown in Figure 7, a current will flow through the conductor 44, the primary of the transformer 45, the conductor 50 to the generator. The induced current will pass through the wire 46, the conductor late 48, the conductor 14, the conductor ring 8 the conductor 23, through the armature of the motor 34, the conductor 21, the conductor ring 6, the conductor 12, through the conductor plate 49, the conductor 13, through the conductor ring 7, the conductor 22, through the field of the motor, and to the ground 52 through a conductor 58. This flow of the current'will actuate the motor 34 and propel the truck member 1 forwardly through its operative connection with the axle shaft 29.

The truck member 1 may be propelled forwardly for the full length of the cable containin the cnductors 21 to 25 inclusive, and

the 09. 1e may be as long as desired. The

operator may steer the truck' member in either direction, i. e.: to the right or to the left, if so desired. The front wheels 39 are current passes through the magnetic coil 35 the steering lever 37 is actuated so as to turn the wheels 39 to the right. By actuating the switch 56 so as to move the switch out of enga ement with the conductor 16 the circuit is roken, which includes the magnetic coil 35 thus releasing the steering lever 37 and allowing the sprlng member 42 to return the front wheels 39 to their normal positions.

By moving the switch 56 into registration with the conductor 15 the circuit is closed allowing the current to pass from the positive conductor, through the switch 56, the conductor 15, through the contact ring 9, the conductor 24, through the magnetic coil 36 and to'the ground '52 throu h the conductor 55. As the current passes through the magnetic coil 36 the steering lever 38 is actuated thus steerin the truck member 1 to the left. If so desire the truck member may continue its movement to the left indefinitely, circling around the garage member 2 and retaining the electrical connection due to the movable member 17 and the electrical connections with the rings 6 to 19 inclusive. Furthermore, the operator may control the truck member so that it may be moved into and out of the garage by the remote control, or moved to any position or throu h any path at any desired distance around t egarage.

f The truck member may also be moved in the reverse direction, i. e. rearwardly, by actuating the reversible switch 47 so as to move the conductor plate 48 into registration with the conductors 13 and 14 and move the conductor plate 49 into registration with the condu'ctors 12 and 46. In this manner the motor 34 is reversed thus moving the truck member 1 in the reverse direction.
